Wind Simulation & Wind Load Generation
With the stand-alone program RWIND Simulation, wind flows around simple or complex structures can be simulated by means of a digital wind tunnel.
The generated wind loads acting on these objects can be imported to RFEM or RSTAB.
In this technical article, a pendulum column with a centrally acting axial force is to be verified by means of the RF-/STEEL EC3 add-on module according to EN 1993-1-2. using the National Annex of Germany.
The design of cold-rolled steel products is defined in EN 1993-1-3. Typical cross-section shapes are channel, C, Z, top-hat, or sigma sections. These are cold-rolled steel products made of thin-walled sheet metal that has been cold-formed by roll-forming or bending methods. When designing the ultimate limit states, it is also necessary to ensure that local transverse forces do not lead to compression, crippling of the web or local buckling in the web of the sections. These effects can be caused by local transverse forces by the flange into the web as well as by support forces at the supported points. Section 6.1.7 of EN 1993-1-3 specifies in detail how to determine the resistance of the web Rw,Rd under local transverse forces.
Utilize the RF-/STEEL Cold-Formed Sections module extension to perform ultimate limit state designs of cold-formed sections according to EN 1993-1-3 and EN 1993-1-5. In addition to the cold-formed cross-sections from the cross-section database, you can also design general cross-sections from SHAPE-THIN.
In this technical article, a pendulum column with a centrally acting axial force and a line load acting on the strong axis is to be determined by means of the RF-/STEEL EC3 add-on module according to EN 1993-1-1.
With RF-/STEEL EC3, you can utilize nominal temperature-time curves in RFEM and RSTAB. The standard time-temperature curve (ETK), the external fire curve and the hydrocarbon fire curve are implemented. Moreover, the program provides the option to directly specify the final temperature of steel.
The following article describes how to create a user-defined antenna bracket which will be used in RF-/TOWER Equipment.
In this technical article, a hinged column with a centrally acting axial force and a linear load that acts on the major axis is designed according to EN 1993-1-1 with the aid of the RF-/STEEL EC3 add-on module. Column head and column base are assumed as a lateral and torsional restraint. The column is not held against rotation between the supports. The cross-section of the column is an HEB 360 from S235.
This article describes the different options to determine the allowable deformation of crane runway girders. Since multi-span beams and flexible lateral supports (sway bracing) are used in practice, this article will show how to select the correct method.
A welded connection of a HEA cross-section under biaxial bending with axial force will be designed. The design of welds for the given internal forces according to the simplified method (DIN EN 1993-1-8, clause 126.96.36.199) by means of SHAPE-THIN will be performed.
The following technical article describes the creation of a user-defined platform for use on a four-sided tower in the RF-/TOWER add-on modules. First, start with an empty model of the type 3D and define four nodes. The numbering and position of these nodes are very important here.
